. RUNNiNiE' GEAR FOR VEHICLES.

SPECIFICATION forming part of Letters-.Patent-No. 658,308, dated septel'nber l 8," 1"9 '0 Applloetionfilediliay 14,1900. Serlal to. 16,597. imm ral-J r To all whom it maly concern.- a 4 Be it known that I, GEORGE M. Wool), of the city of Deoatur,county of Macon. and State of Illinois, haveinvented certain new and new f ul Improvements in RnnningGear for Vehielse, of which the following is a specification: This invention is intended to facilitatethe travel of wagons, carriages; automobiles, and the like. It is exemplified in the structure hereinafter described, and it is defined in the appended claims. 7

In the drawings forming part of this specification, Figure 1 is a side elevation of a wagon embodying my improvements,the near wheels of the wagon being removed to better show the construction. Fig. 2 is a rear elevation of the rear end of the wagon. Fig. 3 isa detail of a fragment of a tread-wheel and of a load-carrying wheel therein, the tread-wheel being partly broken away to show peculiarities ofits construction.

In constructing the particular embodiment of my invention shown in the drawings a set of tread-wheels 1 and 2 are made with in wardly-extending flanges on their follies, as shown at 1 in Figs. 2 and 8. The axles 5 and 6 of the two pairs of tread-wheels are connected by means of an ordinary reach or coupling-pole 3, and the tongue 4 is connected with the front axle 6. Upon the flanges of the tread-wheels are mounted a set of loadbearing wheels 7 and 11-, such wheels having their faces shaped to embrace the flanges of the tread-wheels, and, the wheels 7 and 11 turn on axles 8 and 12, respectively. Yokeformed supports 9 are fastened onto the rear axle 8, and they extend upward to the wagonbox 10. Similar supports 13 are fastened onto axle 12, and they extend upward to a fifth Wheel or bolster 14, which is connected with the bed or box. The supports for the bed straddle the axles of the tread-wheels out of contact therewith, and they rise above these axles sufficiently far to hold the bed out of contact therewith, and so the bed audits load are supported entirely from axles 8 and12.

Wheels 1 and 2, axles 5 and 6, reach 3, and tongue 4 constitute a tread and draft structure.

amount of independent'horizoiital motion lengthwise of. the wagon, and-this is an esw sential condition. r

As the draft structure is moved forward or i.

backward the inertia of the load detains the load-bearin g structure/until the wheels thereof are raised somewhat from their shown lowest position, after which wheels '7 and 11 roll down constantly; forming inclines on the flanges of the tread-wheels; and keep pace with the travel of the treadwvheels.

The structure of the vehicle in regard to shape, form, and proportions is immaterial, as is also-the means employed to move the vehicle.

What I claim as new, and desire to secure by Letters Patent, is-

,1. A vehicle consisting of a draft or propulsion truck the wheels of which have flanges on their rims, and a load-bearing truck the wheels of which run inside the wheels of the draft-truck on the flanges thereof; the two trucks having independent motion lengthwise of the vehicle, substantially as described.

2. In a vehicle, the combination of a draft truck composed of tread-wheels, axles therefor and a coupling-pole, and a load-bearing truck composed of wheels running on flanges of the tread-wheels and journaled on axles, a body and supports for the body rising from the load-bearingaxles and straddling the axle of the draft-truck, substantially as set forth.

In testimony whereof I sign my name in the presence of two subscribing witnesses.

GEORGE M. WOOD.

If is hereby certified chat in Letters Patent No. 658,308, granted September 18,1900, upon the application of George M. Wood, of Decatur, Illinois, for an improvement in Running-Gear for Vehicles, errors appear-in the printed specification requiring correction, as fol lowez In line 67, after the word constantly and line 68, after the compound word tread-whee1sthe commas should be stricken out; and that the said Letters Patent should be read with these corrections therein that the some may conform to the record of the casein the Patent Office.
